Migrations addManyToManyInverseRelation not working

[vytsci]

I need to make these changes:

/**
     * @param Schema $schema
     * @param QueryBag $queries
     * @throws \Doctrine\DBAL\Schema\SchemaException
     */
    public function up(Schema $schema, QueryBag $queries)
    {
        $opportunityTable = $schema->getTable('orocrm_sales_opportunity');
        $applicationTable = $schema->getTable('oro_claims_application');

        $opportunityTitleColumnNames = $opportunityTable->getPrimaryKeyColumns();
        $opportunityDetailedColumnNames = $opportunityTable->getPrimaryKeyColumns();
        $opportunityGridColumnNames = $opportunityTable->getPrimaryKeyColumns();
        $applicationTitleColumnNames = $applicationTable->getPrimaryKeyColumns();
        $applicationDetailedColumnNames = $applicationTable->getPrimaryKeyColumns();
        $applicationGridColumnNames = $applicationTable->getPrimaryKeyColumns();

        $opportunityAssociationName = ExtendHelper::buildAssociationName(Opportunity::class);
        $applicationAssociationName = ExtendHelper::buildAssociationName(Application::class);

        $this->extendExtension->addManyToManyRelation(
            $schema,
            $opportunityTable,
            $applicationAssociationName,
            $applicationTable,
            $applicationTitleColumnNames,
            $applicationDetailedColumnNames,
            $applicationGridColumnNames,
            [
                'extend' => [
                    'owner' => ExtendScope::OWNER_SYSTEM,
                    'target_entity' => Application::class,
                    'target_field'  => 'id',
                    'bidirectional' => true,
                    'without_default' => true
                ]
            ]
        );

        $this->extendExtension->addManyToManyInverseRelation(
            $schema,
            $opportunityTable,
            $applicationAssociationName,
            $applicationTable,
            $opportunityAssociationName,
            $opportunityTitleColumnNames,
            $opportunityDetailedColumnNames,
            $opportunityGridColumnNames,
            [
                'extend' => [
                    'owner' => ExtendScope::OWNER_SYSTEM,
                    'target_entity' => Opportunity::class,
                    'target_field'  => 'id',
                    'bidirectional' => true,
                    'without_default' => true
                ]
            ]
        );
    }

ManyToMany will be created as it should, but inverse side later throws exception on file vendor/oro/platform/src/Oro/Bundle/EntityExtendBundle/ORM/RelationMetadataBuilder.php:59 That target entity does not exist $configRelationEntity = $this->configManager->getEntityConfig('extend', $relation['target_entity']); Ive tried many combinations, but I was unable to generate proper Inverse side relation.

On file vendor/oro/platform/src/Oro/Bundle/EntityExtendBundle/Migration/Extension/ExtendExtension.php from Ive changed addManyToManyInverseRelation method a bit

        $selfFieldId = new FieldConfigId(
            'extend',
            $selfClassName,
            $associationName,
            RelationType::MANY_TO_MANY
        );

        $targetFieldId = new FieldConfigId(
            'extend',
            $targetClassName,
            $targetAssociationName,
            RelationType::MANY_TO_MANY
        );

        $selfTableOptions['extend']['relation.' . $selfRelationKey . '.field_id'] = $selfFieldId;
        $selfTableOptions['extend']['relation.' . $selfRelationKey . '.target_field_id'] = $targetFieldId;
        $selfTableOptions['extend']['relation.' . $selfRelationKey . '.owner'] = true;
        $selfTableOptions['extend']['relation.' . $selfRelationKey . '.target_entity'] = $targetClassName;
        $this->extendOptionsManager->setTableOptions(
            $selfTableName,
            $selfTableOptions
        );

        $this->extendOptionsManager->mergeColumnOptions(
            $selfTableName,
            $associationName,
            ['extend' => ['bidirectional' => true]]
        );

        $targetTableOptions['extend']['relation.' . $targetRelationKey . '.field_id'] = $targetFieldId;
        $targetTableOptions['extend']['relation.' . $targetRelationKey . '.target_field_id'] = $selfFieldId;
        $targetTableOptions['extend']['relation.' . $targetRelationKey . '.owner'] = false;
        $targetTableOptions['extend']['relation.' . $targetRelationKey . '.target_entity'] = $selfClassName;
        $this->extendOptionsManager->setTableOptions(
            $targetTableName,
            $targetTableOptions
        );

Ive added target_entity for both relations, Im still checking if everything works, If so Ill make PR.
